Be it known that I, WILLIAM C. GeN- NELL, a citizen of the United States, residing at Cadiz, in the county of Harrison and State of Ohio, have invented certain new and useful Improvements in Tire-Detlating Tools; and I do hereby declare the following to be a full, clear, and exact description.. of the invention, such aswill enable others skilled in the art to which it appertains to make and use the saine. Y

This invention relates to devices for del Hating pneumatic tires, and one of the principal objects of the invention is to provide a clasp of simple constructionto be attached to the threaded end of the nipple and for holding the check valve unseated so that the air from the tire will escape.-

. vAnother object of the invention is to provide a simple clasp to be connected to a nipple for holding the valve unseated, said clasp being made of tivo parts having a projecting integral member for holding the valve unseated, said clasp having a spring to hold the aws connected with the nipple.

The foregoing and other objects may be attained by means of the construction illiiso trated 1n the accompanying drawing, in which, Figure 1 is a sectional view of a clasp connected to a check valve nipple and showing a' portion ot' an automobile tire, Fig. 2 is a plan view of the clasp or tool for deflating the tire.

Referring to the drawing, the numeral 1 l designates the nipple 'of a pneumatic tire and 2 is the check valve therein, while S is the threaded outer portion of the nipple;

The de'lating tool or device consists of a clasp comprising two members l and 5 preferably made of sheet metal and provided with inwardly turnedpintle bearings 6. 7 of the clasp are turned inwardly and rounded to .tit the threaded v portion of the nipple, said rounded portions fitting in the threads so that they can be turned and moved inwardl)7 and outwardly as required.

The member 4t *of the clasp is provided with an integral tongue 8, the ends of which are bent angularly, as at 9 and said tongue is disposed practically in the center between vthe two members 4f and 5 tobear upon the stem 1i) of the check valve and to hold the valve unseated while the tire is being de- Hated. A spiral spring 1 1 surrounds the pintle 12- and bears against the finger4 holds 13 upon their inner sides.

Theoperation of the invention will beA readily understood li't'rom the foregoing. l/Vhen the tool is engaged with the nipple, the tongue 8 isdisposed in the center in line with the stem 10 of the, check valve, and upon turning the clasp, the tongue bears upon the stein 10 and holds the valve vun'- seated, vwhile the air escapes.

The invention is'sirnple in construction, canbe readily placed in position for use,

can be manufactured at low cost and is very efficient for its purpose.

Various changes may be made inthe ,details Of 'construction without departing from the spiritand scope of the invention as defined in the claim.

That is claimed is 1 The herein described tire dellating tool comprising a clasp consisting of two members pivotally connected together and provided with jaws and a spring for forcing' 'WiLLiAM o. GUNNELL.
